GRADUATED-SPACING TABLE.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed April 9, 1909. Serial No. 488,959.

To all whom it may concern:

Be it known that I, THOMAS V. BOYLE, a citizen of the United States,residing at Cleveland, in the county of Guyahoga and State of Ohio, haveinvented certain new and useful Improvements in Graduated-SpacingTables, of which the following is a specification.

My invention relates to graduated spacing tables for use in punchingangle irons, rails and other work, to locate the holes without firstmarking the same upon the work, and my object is to provide certainnovel features of construction and arrangement which will be hereinafterspecifically designated and referred to.

In the accompanying drawings which illustrate my invention, and form apart of this specification, Figure 1 is a side elevation of a deviceconstructed in accordance with my invention and broken away. Fig. 2 is across section therethrough on line 1919 of Fig. 1. Fig. 3 is a detailplan view of a portion of the graduated table. Fig. 4: is a detailsectional view through the lower bracket and table. Figs. 5 and 6 aredetail perspective views of the stop blocks, and, Fig. 7 is a detailperspective view of one of the adjustable shaft bearings.

Referring specifically to the drawings, a carriage 1 travelslongitudinally upon the upper edges of vertical spaced side members 16,constituting the stationary frame, one of which side members 16 has ahorizontal outstanding table 8, and the carriage 1 having an outstandinghorizontal bracket 2, above said table 8 and parallel therewith. Thecarriage 1 further has a clamping device 1 to clamp the work and feedthe same beneath the punch 15 upon the movement of said table, which iseffected by means of a handle 7 at the extremity of its bracket 2.

The carriage bracket 2 has a plurality of vertical openings 2, enlargingdownwardly, and upstanding ears 5 adjacent each of said openings, towhich ears 5 are intermediately pivoted controlling levers 3, havingdepending controlling bars 6 loosely secured at their upper ends theretoat one side of the pivot, which bars have flaring lower ends 6 Levers 3also have counter balancing weights & upon their ends at the oppositesides of their pivots, to hold the said ends downwardly against anupstanding ledge 2 of bracket 2, when said levers are moved to thehorizontal position shown in full lines in Fig. 4, it being understoodthat a selected lever is moved downwardly to lower its bar 6.

The table 8 has a plurality of longitudinal parallel channels 17, in itsupper face, corresponding to the number of levers 3, each of whichchannels 17 has a plurality of circular apertures 17 equally spacedapart as shown by reference to scale 17 These openings are adapted forthe reception of the stop blocks 9, shown in various shapes in Fig. 3,and comprising, as shown in Figs. and 6 a cylindrical body 9 and a head9*, which may extend from one side of the center of said body, the body9 being inserted in openings 17*, with heads 17, resting in, andprojecting above the channels 17 into the path of its corresponding bar6.

In punching long work, a shaft 14: extending transversely between thesides 16 of the stationary frame, and provided with rollers 10, may beutilized to feed such work, the ends of said shaft resting in journalblocks 13, having diagonal side flanges 13 for engagement in selectedones of the vertical se ries of diagonal slots 12 in the opposing facesof spaced parallel vertical beams 11 secured upon the inner surfaces ofthe said frame sides 16, and thus rendering said shaft verticallyadjustable to accommodate different sizes of work.

Thus in use, a rail or other work having been clamped in the device 1,and stops 9 having been placed within various openings 17, in channels17, according to the desired spacing of the openings to be punched inthe work, and the corresponding bar 6 having been depressed by downwardmovement of its lever 3, the carriage 1 is moved until bar (3 engagesthe first stop 9, when the first punching operation takes place. Shouldthe spacing for a certain hole, be say, two and three-eighths inches, astop block 9 having an offset head 9 is placed in the three-inch holewith its head extending five-eighths of an inch in advance thereof,(going by the graduation 17). By the employment of a plurality ofchannels and levers, and the structure thereof and of the steps, I amthus able to provide for a number of jobs, which may be continuously runthrough, or one job may be set up or spaced while another is be ingpunched. Further, levers 3 are as shown in Fig. 1, of different lengths,in order that the inner ones may be readily grasped, and inasmuch asbars 6 have slight sidewise movement in their tapering openings 2thecarriage is stopped with the opening directly above the stop block.

From the foregoing, it will be seen that the carriage may be moved ineither direction to feed the work beneath the punch.

Having fully described my invention, I claim:

1. In a spacing machine of the character described, the combination witha movable carriage having means to clamp the work, of a spacing tableprovided with a plurality of longitudinal parallel slots, and withopenings therethrough in said slots, a plurality of stop members,corresponding in number to said slots, carried by said carriage, aplurality of stop blocks for insertion within se lected openings in saidslots, and means for independently moving said carriage stop membersinto, and out of, the path of said stop blocks.

2. In a spacing machine of the character described, the combination of aspacing table having a plurality of longitudinal parallel slots, andopenings therethrough in said slots, a plurality of stop-blocks,comprising body portions for engagement in selected ones of saidopenings, and varyingly shaped heads extending upwardly out of saidslots, and a movable carriage having elements to contact with said headsof said stop blocks.

8. In a spacing machine of the character described, the combination of aspacing table having a plurality of longitudinal parallel slots, andequi-distantly spaced openings therethrough within said slots, aplurality of stop blocks comprising body portions for engagement inselected ones of said openings, and heads carried by said body portionsand projecting upwardly out of said slots, certain of said blocks havingtheir heads ofiset from their body portions, and a movable carriagehaving elements to contact with said heads of said stop blocks.

4. In a spacing machine of the character described, the combination of aspacing table having a plurality of longitudinal parallel slots, andopenings therethrough, within said slots, stop blocks for insertionwithin selected ones of said openings to project out of said slots, amovable carriage having a portion thereof projecting above said tableand provided with vertical openings therethrough alined with said tableslots, contact bars depending through said slots, levers pivoted uponsaid carriage portion to which said contact bars are connected toproject the same into, and out of, the path of said stop blocks, andcounter-balancing weights carried by said levers.

5. In a spacing machine of the character described, the combination of aspacing table having a plurality of longitudinal parallel slots, andopenings therethrough within said slots, stop blocks for insertionwithin selected ones of said openings to project out of said slots, amovable carriage having an outstanding bracket projecting above saidtable and provided with a series of vertical downwardly enlargingopenings alined with said table slots, levers pivotally mounted uponsaid bracket independent of one another and provided withcounter-balancing weights, and bars pivotally connected to said leversand depending therefrom through said bracket openings and movable into,and out of, the path of said stop blocks.

6. In a spacing machine of the character described, the combination of aspacing table, a movable carriage, relatively engageable stop memberscarried by said table and said carriage, means carried by said carriageto clamp the work, a frame upon which said carriage moves embodyingvertical side members, a roller shaft for the work, extendingtransversely between said side members, and journals for the ends ofsaid shaft, vertically adjustably mounted upon said side members.

In testimony whereof I aflix my signature, in presence of two witnesses.
